Decrease: effectiveness of oral contraceptives

Drug/Herb

o Do not use acidophilus with antiinfectives; separate by several hours

Decrease: absorption—khat; separate by 2 hr

Drug/Lab Test

False positive: Urine glucose, urine protein, direct Coombs' interview

NURSING CONSIDERATIONS

Assess:

o I&O ratio; report hematuria, oliguria, since penicillin in high doses is nephrotoxic

o Any patient near a compromised renal system, since drug is excreted slowly in poor renal system function; toxicity may occur rapidly

o Hepatic studies: AST, ALT

o Blood studies: WBC, RBC, Hgb and Hct, bleeding time

o Renal studies: urinalysis, protein, blood, BUN, creatinine

o C&S earlier drug therapy; drug may be given as soon as culture is taken

o Bowel pattern before, during treatment; diarrhea, cramping, blood contained by stools, report to prescriber; pseudomembranous colitis may occur

o Skin eruptions after administration of penicillin to 1 wk after discontinuing drug

o Respiratory status: rate, character, wheezing, tightness within the chest

o Anaphylaxis: rash, itching, dyspnea, facial/laryngeal edema

Administer:

PO route

o Shake suspension well before respectively dose; may be used alone or mixed in drinks; use immediately; discard unused portion of susp after 14 days

o Give around the clock, caps may be empty and mixed with liquids if needed

Perform/provide:

o Adrenaline, suction, tracheostomy set, endotracheal intubation equipment on unit

o Adequate intake of fluids (2 L) during diarrhea episodes

o Scratch testing to assess allergy after securing order from prescriber; usually done when penicillin is only drug of choice

o Storage in tight container; after reconstituting, oral suspension chilled for 14 days

Evaluate:

o Therapeutic response: absence of infection; prevention of endocarditis, resolution of ulcer symptoms
